LM=MN²+LN²
9²=X²+6²
81=X²+36
-x²=36-81
ײ=36+81
ײ=117
x=10
Answer:
6
Step-by-step explanation:
as you see that for Triangle are both congruent, both | CA= | AB
8=8 so when you look at the smaller circle, LM=MN
and plug in the numbers,
making 6=x

Bonnie is n years old.
Clara is three times as old as Bonnie.
Danesh is seven years older than Bonnie.
The total of Bonnie's age, Clara's age and Danesh's age is T years.
Find a formula for T in terms of n.
Answer:
T = 5n + 7
Step-by-step explanation:
Bonnie : n
Clara : 3n
Danesh : 7 + n
T = n + 3n + 7 + n
T = 5n + 7
6x - 8y = 12 and 5x + 8y = -1 Solve using elimination
Answer:
Step-by-step explanation:
6x-8y=12
5x+8y=-1
add them
11x=11
x=1
y=-3/4
Answer:
(1,-3/4)
Step-by-step explanation:
Luckily, y is already opposites, so it should be easier:
6x-8y=12
5x+8y=-1
Combine; This should end up with y eliminated -
11x = 11
x = 1
Now we can plug 1 in for x in one of the equations to find y. I'm going to use the second one.
5(1) +8y = -1
5+8y=-1
8y=-6
y=-6/8 (you can simplify)
The point at which the lines intersect is (1,-3/4)
50 points!! I will mark brainliest to the correct answer :) please don’t put random answers... they will be reported. Thanks!
Step-by-step explanation:
Answer for the first question.
since the triangles are congruent so angles and sides are also congruent I.e. sides and angles are equal then,
3x - 3 = 12
3x = 12 + 3
3x = 15
x = 5
55° = 7x + y
55° = 7 * 5 + y
35° + y = 55°
y = 55° - 35°
y = 20°
Answer for the second question,
x + 70° = 2x - 2° {Exterior angle of a triangle is equal to the sum of two opposite interior angles }
2x - x = 70° + 2°
x = 72°
Now
<WXY = 2x - 2°
= 2 * 72° - 2
= 142 °

Jimmy and Kima are going on a trip. They will drive for three days. The first day they will drive 182 miles. The second day they will drive 439 miles. The third day they will drive 217 miles.
Which expression is the closest estimate of how many miles Jimmy and Kima will drive on their trip?
options.
150 + 400 + 200
200 + 400 + 200
200 + 450 + 200
200 + 500 + 200
Answer:
200 + 400 + 200
This is because you always round up past 50 and down under 50 so.
182->200
439->400
217->200
find the sum of the 2 terms of an A P are in the ratio of (2n-1):(2n+1) then find the ratio of their 10th term
Answer:
37/39
Step-by-step explanation:
We know that formula for n terms of an AP is written as;
(n/2)(2a + (n - 1)d)
Let the sum of the first AP be;
(n/2)(2a + (n - 1)d)
Let the sum of the second AP be (n/2)(2A + (n - 1)D)
We are told that they have a ratio of (2n-1):(2n+1)
Thus;
(2n-1)/(2n+1) = [(n/2)(2a + (n - 1)d)]/[ (n/2)(2A + (n - 1)D)]
On RHS, n/2 will cancel out to give;
(2n-1)/(2n+1) = [(2a + (n - 1)d)]/[(2A + (n - 1)D)]
Rewriting this we have;
(2n - 1)/(2n + 1) = [(a + ½(n - 1)d)]/[A + ½(n - 1)D)]
But we want tod find;
(a + (n - 1)d)/(A + (n - 1)D)
Thus,at n = 10, we have;
(a + 9d)/(A + 9D)
Comparing with [(a + ½(n - 1)d)]/[A + ½(n - 1)D)], we can say that;
½(n - 1) = 9
n = 18 + 1
n = 19
Thus;
(a + 9d)/(A + 9D) = (2n-1)/(2n+1)
Putting n = 19 gives;
(a + 9d)/(A + 9D) = (2(19) - 1)/(2(19) + 1)
(a + 9d)/(A + 9D) = 37/39

there were 62 people in the movie theater for the matinee. ticket sales for that showing were $364. if adult tickets cost $7 and children tickets cost $3.50, how many of each were at that show. please solve with systems of equations.
Answer:
Step-by-step explanation:
a+c=62, c=62-a
7a+3.5c=364, using c found above gives you
7a+3.5(62-a)=364 expand left side
7a+217-3.5a=364 group like terms on left side
3.5a+217=364 subtract 217 from both sides
3.5a=147 divide both sides by 3.5
a=42, since c=62-a
c=62-42=20
So 20 children and 42 adult tickets were sold.

For her phone service, Maria pays a monthly fee of $19, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is $72.35. What are the possible numbers of minutes she has used her phone in a month? Use m for the number of minutes, and solve your inequality for "m".
Answer:
m=1067
Step-by-step explanation:
19 +.05m = 72.35
72.35-19 = 53.35
53.35/.05= 1067
m=1067

explain
Answer:
yes because the hours to distance is moving at a constant rate and if you were to graph it, it would also go through the origin
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
This table is not proportional because the outputs do not get their answer using the same equation. The first to inputs and outputs ([tex]\frac{1}{2}[/tex] and [tex]\frac{1}{4}[/tex]; 1 and [tex]\frac{1}{2}[/tex]) are proportional. You multiply the input (distance) by [tex]\frac{1}{2}[/tex] to get the output (hours). The final option of input and output ([tex]2\frac{1}{2}[/tex] and [tex]1\frac{1}{4}[/tex]) is not proportional.

Answer:
[tex]x=4[/tex]
Step-by-step explanation:
By the Triangle Proportionality Theorem:
[tex]\displaystyle \frac{x}{12}=\frac{x+1}{15}[/tex]
By cross-multiplication:
[tex]\displaystyle 12(x+1)=15(x)[/tex]
Distribute:
[tex]12x+12=15x[/tex]
Subtract 12x from both sides:
[tex]12=3x[/tex]
Hence:
[tex]x=4[/tex]
Answer:
4
Step-by-step explanation:
The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.
Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:[tex]\frac{x}{x + 12} = \frac{x + 1}{x + 16}[/tex] **
We now multiply both sides of the above equation by [tex](x + 12)(x + 16)[/tex] to get: [tex]x(x + 16) = (x + 1)(x + 12)[/tex]
[tex]x^{2} + 16x = x^{2} + 13x + 12[/tex]
[tex]3x = 12[/tex]
[tex]x = 4[/tex]
That means our answer, for the value of x, is 4
** Make sure you don't say [tex]\frac{x}{12} = \frac{x + 1}{15}[/tex], because those aren't the sides of the larger square.
